3) A cheetah is hunting. Its prey run for 2.5 s at a constant velocity of +6.9 m/s. Starting from rest, what constant acceleration must the + cheetah maintain in order to run the same distance as its prey runs in the same time?

4) An astronaut on a distant planet wants to determine its acceleration due to gravity. The astronaut throws a rock straight up with a velocity of +12.1 m/s and measures a time of 18.5 s before the rock returns to his hand. What is the acceleration (magnitude and direction) due to gravity on this planet?
(positive = up, negative = down)

(^ stands for exponent)

Distance traveled by the prey = s = v t = 6.9 m/s. x 2.5 s = 17.25 m
